ELASTIC STOCKING.

SPECIFICATION forming part of Letters Patent No. 250,154, dated November29, 1881, Application filed August 31, 1881. `(Model.)

To all whom it may concern Be it known that I, DAVID D. M. MASTER, ofFlushing, in the county of Queens and State of New York, have inventedcertain new and useful Improvements in Elastic Stockings; and I dohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart 'to which it appertains to make and use the same, 1o reference beinghad to the accompanying drawings, which form a part of thisspecitication.

Figure l is a side view. Fig. 2 is a vertical sectional view on the linex, and Fig. 3 is a horizontal sectional view of one of my improvedstockings.

Corresponding parts in the several figures are denoted by like lettersof reference.

This invention relates to elastic stockings and other bandages forvarious lnedical and 2o surgical purposes; and it consists in certainimprovements in the construction of the same, which will be hereinafterfully described, and particularly pointed out in the claim.

Elastic bandages as heretofore constructed 2 5 have been open to aserious objection-viz., that in pulling them on or oft' they wouldstretch longitudinally or in the direction of the pull, thus impairingthe lateral or circumferential elasticity, making the adjustmentdiflicult and painful, and causinga very considerable and unnecessarywear to the article. By my present invention these objections areremoved or reduced and a superior and desirable article furnished. 3 5In the drawings hereto annexed, Arepresents my invention as applied toan elastic stocking, which is made, in the usual manner, of any suitableelastic fabric, silk, cotton, or other material being employed as acovering for the elastic strands or threads, which are woven in theusual manner, so as to form a suitable porous fabric. Along the entirelength of the cylindrical or tubular fabric formin g the stockingleg Isecure, on each side, a pair of non-elastic but flexible stays, B B,which absolutely prevent any longitudinal stretching of theelasticfabric, while the lateral expansion is in no wiseimpaired. Bythis construction the stockin g or bandage may be easily and painlesslypulled on or off, and the wear caused by the 5o longitudinal pull uponthe material is entirely avoided.

The longitudinal strips or stays B may be stitched or otherwise securedupon the outside of the tubular fabric, or they may be woven therein, ifso preferred. The latter construction may be preferably, but notnecessarily, adopted.

I am aware of the patent to Molesworth for improvements in dilators,granted December 6o 1, 1874. This is a rubber bag provided withlongitudinal inelastic cords or wires, to prevent longitudinal expansionwhen the bag is inflated. This, however, is not only a differentarticle, but so far different from the present invention that expressprovision is made for the prevention of lateral expansion at the end,which is absolutely necessary in this case.

I am also aware that a longitudinal inelastic stay has been and is beingused upon the 7o back of elastic stockings. This I have evenv shown inthe drawings hereto annexed. Itis evident, however, that such stay isutterly inefficient for thepurpose of preventing longitudinal stretchingwhen the stocking is pulled 7 5 on or off, the pull being on the sidesand evenly distributed. N or would a single stay on each side answer,because in order to render it of any use it would have to be so wide asto interfere with the porosity of the bandage. The 8o non-porousdilating bag and the single stay I disclaim; but,

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- As an article of manufacture, anelastic porous tubular bandage provided on each side with a pair ofnarrow non-elastic but flexible longitudinal stays, as described, forthe purpose set forth. 9o

In testimony thatIclaim the foregoing as my own I have hereto ailixed mysignature in presence of two witnesses.

DAVID D. M. MASTER.
